Because detention houses are small and there are many of them, they can provide the right housing for each individual to fulfil his or her potential. This is what differentiation means: placing individuals within an appropriate context based on their specific needs and circumstances. This can be achieved by tailoring the level of security, not based on the traditional low-medium-high classification, but rather according to an individual’s gradual regain of autonomy. The high-security levels that characterize large prisons are only required for a few individuals and inevitably make the reintegration process much more challenging. Differentiated facilities provide comprehensive and personalized support, through services, activities and programs that prepare individuals for their eventual release into society. Through making use of shared services in the community, it becomes more feasible and cost-effective to tailor the time in detention to the individual’s needs.
